Subject: Re: [4.4/4.5 regression] IRA apparently
systematically making reload too busy on 2 address instructions
with 3 operands
Thanks, we should see if this solves the AMMP problem in a day or two.
Are you going to look at the related PR42961? Without the regmove hunk
it does not happen at AMMP but it likely happens elsewhere. I did some
work on this years back on old RA so I can play with it too.
(Simple fix would be to add ? penalizers to integer variant of FP moves,
but I would like to see some solution where RA actually can use integers
for mem->mem copies)
